bug#26946: Failed test report for coureutils-8.27

[Paul Eggert]

Thanks, that's merely a bug in the test case, not in coreutils itself. 
The bug was fixed here:

http://git.savannah.gnu.org/cgit/coreutils.git/commit/?id=612086660bab9bf981894da146550e9101224b17
and this fix should appear in the next release.
